STEREO LINE INPUT
Remote START/STOP – Normal vs. EFS
Slide switch SW1 (mounted on the main PCB just to the left of the top
of the module’s fader) affects the way channel ON/OFF switches send
control signals to START and STOP remote source machines.
When SW1 is set to NORMAL (“up”) whenever the channel ON
switch is pressed a single pulse closure takes place at the A and B START
ports. When the OFF switch is subsequently pressed, a single pulse closure
takes place at the A and B STOP ports.
When set to EFS ON (“down”) a “European fader start” type of
constant closure is activated: whenever the channel ON switch is pressed
momentarily a constant closure is initiated at the module’s A and B
START control ports. When the channel OFF switch is subsequently
pressed, that closure is broken.
If an SLD-5 module has been equipped with an optional EFS-type
fader with a bottom-of-travel switch, it is best to set SW1 to EFS ON.
While no harm will result to any circuitry or hardware if an EFS fader is
used with SW1 set to NORMAL, the end result will be an extremely short
control pulse at the module’s START/STOP control ports—a pulse so short that
it may not be detected by all source machines.
Hook-Ups
As stated before, all user wiring to and from SLD-5 modules takes
place at AMP 12-pin connectors mounted directly beneath each module on
the console mainframe’s bottom pan. There are four connectors per
module: A and B (towards the console meterbridge) handle audio inputs;
C and D (near the console armrest) control signals.
Analog Version Audio Connections (AMP A)
These include A and B source inputs; level is +4dBu balanced.
